The development of a smart software security system by using the PIC16C84 MCU

The PIC16C84 is a low-cost, high performance microcontroller developed by Microchip Inc. It is a fully-static 8-bit microcontroller with 1K/spl times/14 EEPROM program memory and 64 bytes of EEPROM data memory. This paper discusses a feasibility study for the development of a smart PIC16C84-based security system to prevent both illegal multiplication of commercial softwares and illegal data intrusion. The existence of 64 bytes of EEPROM data memory, enables the system to evolve itself dynamically from time to time. This will push the security level to the point where the security system can be arranged to be dedicated to a single-specific PC system and limited users only.
